"Well then, Well then, Guy's & Gal's what do we have here then?

At long last after much waiting, deliberating and working out different scenarios we have entered the "Drobe Zone" (much eerie music and all that, ).

Take 1 second hand 3 door IKEA wardrobe bought off E-BAY for £60, a few bits and pieces that you already have for your indoor garden add a couple of days hard graft and you too can enter the "Drobe Zone" (there goes that eerie music again).

So what do we have in there ? First off the clone & mother section.

Clone Sect -
1 heated propogator,
4 mini Cool White fluroescent lamps
The ones used for fitting under kitchen cabinets.
I can't remember the exact Lumen output of these, it's pretty low around 500 lumens per lamp but they do work as I used these for rooting the cloned plants I got in the system at the moment. You will see them in the pic's.

Some 41mm kitchen waste pipe with a couple of holes drilled in.
This is connected via ducting through flower section to a S&P TD160 intake fan.
We also have a 41mm elbow to take the waste pipe up and out of the clone section into the Mother section up above.

We also have the air pump that operates the Waterfarm, that the Mother plant is kept in.
I hang this on a hook to help stop the vibration, it's quite a noisy little thing.
I have also stuck some of the door draft excluder strip on this just to help stop the vibration.
I have then drilled a hole in the shelf above the pump, to run the Air-Line up to the Waterfarm.

Then we have a "square'ish", hole cut out for the plugs & cables.
I have done the same in all sections of the drobe and simply cover this up with duct tape to make light tight.

I will post explanations with each set of pics, so please bear with me as this will probably take some time.
Due to having to do seperate reply's because of the photo limits on individual posts.
I will let you guy's know when we are done, then feel free to post comments and questions, if any.

P.S
No laughing at my efforts, I aint no DIY'er, .

well mate it puts my diy skills to shame !!!!!!

Next off, we have -

The Mother Section.


We have the Mother plant in a General Hydroponics Waterfarm with clay pebbles.
1 x 125w Envirolight, blue for veging hung using a single Envirolight Reflector.
41mm waste pipe for Air Intake.
I have this running vertically from the clone section, with some holes drilled in for the air to escape.
I drilled 2 tiny holes in the Drobe wall near the top of the pipe, so I can attach the pipe to the Drobe to keep it steady. I done this using garden wire and steady this around the pipe with Duct tape and then I just capped the top also using Duct tape.

I have a 100mm hole drilled in the roof for passive air exchange, running into the flowering section.
I have a 100mm duct connector tube in this hole to help connect the ducting out the mother section and into the flowering section.
I have put a slight bend on this to act as a light trap, and it works.

Now the best part -

The Flowering Section.

1 x 125mm Charcoal Filter
1 x 125mm RVK Fan, for extraction
1 x 100mm S&P TD 160, for intake
1 x 600 HPS light with Gro-Lux bulb
1 x Cool-Shade
1 x Quantum-Hydro 8 plant trough.

Lets start with the air intake -
I drilled and sawed a 100mm intake hole in the Drobe floor, I lined this with a 100mm duct connector tube. I covered this hole with a pair of the Mrs's tights to act as a filter to stop anything getting sucked into the fan.
I secured the tube in place with NoNails and Duct tape.
I then ran a small piece of 100mm Ducting to the fan and secured each end with tape. I have the fan sat on a decorators sponge, just to absorb the vibration. Works a treat.
On the other end of the fan, more 100mm ducting hung up on the wall by way of a couple of small holes drilled in the Drobe wall and secured with garden wire.
I have cut a few holes in this Ducting to let the air flow into the flower room. I placed some Duct tape over the ducting first before I cut the holes with a pair if scissors, to stop the Ducting foil ripping.
I then cut another 100mm hole in the Drobe on the opposite side to run the Ducting through to the Mother & Clone section.

Charcoal Filter, Fan & Cool-tube Set Up -

I got a Filter hanging kit, for the obvious purpose of hanging the filter, .
Easy enough, mark where you want it to go, drill a couple of small holes to get the screws started and get the screwdriver out.
I done pretty much the same with the 125mm fan.
I then have the Filter & Fan connected using a Fast-Clamp, dead easy.
Then we have a metre or two of ducting coming from the blowing side of the fan to the Cool-Tube then another metre or two of ducting running up to a 125mm hole drilled and sawn into the roof of the drobe for the air-extraction.
I just run the ducting up and out of this hole, I have it sealed around the edges of the hole up above, (on drobe roof) with Duct tape.
The ducting then runs up to an air-brick in the wall.
On the other side of the Drobe roof, next to Fan & Filter I have drilled and sawn another 125mm hole with a 125mm duct connector to keep it tidy and make life easy for getting the Ducting connected.
This is to bring the air in, from the Mother and Clone section.

I sealed the door's using draft excluder, easily available from any DIY shop.
I also included a locking mechanism on the doors to help the draft ecluder do it's job.
This simply consists of a screw eye "thingy", screwed into the top of the door and a holed drilled in the Drobe directly above the eye of the screw "thingy" and a large nail or screw.
You just simply close the doors of the Drobe and slide the nail into the hole on the roof and down into the eye thing, and this holds the doors closed.


I think that, that is about it.
Oh, forgot to say, also gave the inside of the Drobe two coats of white paint before I started.

Any questions, just holler.

Last couple.

Nice! I like a bit of drobe action

BU

Great piece of work there dude

Thanks Dude's for the comments.

Church, I would like to say that I took my inspiration from your Drobe. Hope you don't mind, .

looks spot on that mate.. good work..

Mind? Not one bit, I'm flattered in the extreme. When I posted my Drobe thread, I hoped it would make it a lot easier for other people to pick up the idea and run with it, adapting and improving as they went along. It makes me happy to know that this is happening.

Thank you for your kind words. Keep up the good work.

really nice job with this cab dude... ive not long built my own drobe, though i still need to get the ventilation sorted out...

when i get the cash i will be buying a cooltube reflector, and another inline fan for my intake,,, at the moment all i have is one 100mm RVK fan exhausting the drobe, and i have a hole cut out at the bottom of the cab and have two blower fans blowing fresh air in thru the hole...

i just have a crappy standard reflector on my 400w HPS lamp, and the temps get up to 33C at some points of the day... i think though once i get my cooltube and a decent intake fan these temps should drop down to where they should be...

what are the temps inside ur box may i ask?

Looks great, I am soaking up ideas on wardrobes atm, I fancy a 2 door job split in 2 horizontally with a clone/mum bottom bit and a scrog up top. I am crap at DIY too-it's amazing the skills you find when you want a growbox tho

Another "Drober", there seems to be a few of us around.

Once you get that Cool-Tube and extra fan, you should notice the difference.
My temps varie slightly from day to day, dependent on how warm it is outside but the sort of temps it has been at the last couple of days :-
Max - 31.8. Still a bit warm could do with being lower, but it is a 600 watter in there.
Min - 22.3.

I am considering either getting another RVK 125 fan for to use solely for the cool-tube extraction or getting an RVK 150 and using that for venting the cab & cool-tube? Not sure though. If any experienced "Drober's" out there have any words of wisdom regards this, please let me know.

Thanks for the nice comments, dude.

You are on the right line, in looking at other peep's drobes and soaking all those ideas and info up.
Sounds a good idea splitting in two, will you Bonsai the mum to keep it small ??

Ideally that is what I am looking to do in the near future.
I want to have two halves in there, both for flowering. Then I can harvest around every 4 - 5 wk's.

I am finishing this current grow, which is sort of SOG style, plants are a bit bigger than what I thought for SOG but I vegged them for 3wk's from Cloning.
Next grow I am going to veg for 1wk only and see how tall they grow, if they stay below or around 1/2m then we may have a go'er there.
Then I would have to make a few adjustments to the Drobe, get the fans sitting on the Drobe roof rather than inside etc.


Hopefully your Drobe will all go smoothly for you.

I have a simular set up and also had heat issues, I have carbon filter > rvk 125 > cooltube > attic extraction, I have rvk 100 intake

You can read up about my problems and the solution here

http://www.uk420.com/boards/index.php?show...c=98316&hl=

I guess your main problem is your using warm house air to cool your drobe (I think) you really need to get the air from outside Im pretty sure that wil sort ya temps out.

I bought a 3rd rvk the 150mm L1 version 680m2 per hour, it made very litte difference how I hooked it up, I tried the cooltube on it separate, I tried a straight swap for my 125mm it didnt seem to make much difference at all as far as temps went but the 150mm rvks aint half noisy I got rid of it couldnt be doing with the racket

Another thing is have the lights off when its hottest outside like between 11-5pm or something, now Im in flower my lights are off from 8am to 8pm and my drobe temp is usually about 18/20c during the day and 24/26c at night with lights on.

edit** you can see how I got my fresh air from a window stealthly style here http://www.uk420.com/boards/index.php?s=&a...t&p=1048874

I dont know if its quite relivent, but increseing fan size will ofton make little difference to how much air flows through the unchanged duct work.

fans are measured to two ways. how much air volume they can shift unhindered, and how well they perform against our efforts to make it difficult for them. thats classed as static pressure. its a theoretical measure of how hard it can push against a dead end.


the rub off is that when exhausting through a 6" chimney pot the best fan is an 8" as it will push hardest on that 6" gap. bigger fans shift more air, but they wont push harder on that 6" hole, so are pointless.
when chooseing a fan for a difficult location you really need to read the online spec. A 150mm rvk comes in 3 types, high and lower powered, and high 'umph' which would of been the better choice in a demanding situation. different brands also perform differently.

if i can find some specs i will post them...

the systemair site does hold info, but its badly done. each physical size comes as M L & XL but they only list two of the 3 in each size.

the situation is better with small fans. the high power motor of the 125 being used in the low power 160 to shift more air but only if the holes bigger. no change is static pressure, had they bothered to print it... grrr (major maths involved in checking that one out....so major i roughed it on my fingers. the 125 will probably push a little harder)

upgrading fans should make improvements, but not just size upgrades, there performance levels ( M L or XL ) need to match. its not really size and peak flow numbers that matter though, its the power of the motor unless your ducting is upgraded to match.

Nice drobe... great work

Thanks for the comp's guy's.
Made a few changes to the "Drobe-Zone", since those pics were originally taken.
Changed the fans to 2xAirforce 100 acoustic fans and added a TW2 Fan speed controller and re-arranged the air intake slightly.

I now have the in-take fan sitting above the mother section.
I drilled some holes in the shelf above the mother's (where the fan sits) the theory behind this....being that the fan will suck the air up from the mother section.
I have also drilled a 20cm hole in the drobe roof, slightly off-centre and above the fan, the theory being that the fan sucks the fresh air in from above.....seems to work a treat.
The air then comes down through the mother & clone section through some black soil pipe (guttering) that I drilled some holes in.....to let the fresh air flow into the mother section.
This pipe then goes under the mother & clone section where I used a ducting bend piece to direct the pipe to a 90 degree angle so it runs flat (Parralel to the floor).
This then joins up to another piece of black soil pipe with more holes drilled in.....to bring the fresh air into the flowering section.
You will see what I mean in the pics.

For extraction, I have another Airforce 100 connected to a Phat filter and ducting. This in turn, is connected to the cool-tube and some more ducting. The ducting then runs up and out of the drobe through another hole drilled in the roof and this in-turn then runs up and out of the room via an air brick in the wall.

The fans are more compact, powerful and quieter. The drobe holds a good temperature now averaging between 25 - 28, depending on how high I have them turned up and obviously ambient air-temps.

how are you finding the tw2 controller working alongside your airforce fans,is there any noticeable droning sound when the fans are slowed down?

reason i ask is i got 2 8 inch airforce fans and got a spare prima controll laying around and as a prima controls 2 fans where the airforce controller only controls 1 fan but has another socket for a fan but is not good for me as both fans are the same size so think the prima will work better for me.

Can't really say I hear any droning, seems to work a treat.
